Abstract
The utility model discloses the well mouth sealing devices that gasket ring has radial seal function, it includes left flange (4), right flange (5), gasket ring (3), stud (2) and liftout bolt (6), left flange (4) is connect by stud (2) and liftout bolt (6) through gasket ring (3) integral with right flange (5), it is characterized in that: the axial end face of gasket ring (3) sets boss (7) respectively, left flange (4), gasket ring slot (1) is set respectively on the contact surface of right flange (5), the groove (8) of boss (7) is closed in the bottom establishing of gasket ring slot (1), gasket ring (3) is mounted in gasket ring slot (1), the boss (7) of gasket ring (3) fits snugly in the groove (8) of gasket ring slot (1).The utility model is interference fitted by the groove of the boss of gasket ring and the gasket ring slot of flange, is avoided not tightening because of nut or be leaked caused by gasket ring sealing surface has scratch, solves the problems, such as wellhead sealing, improve the sealing performance of flange.
Description
Technical field
The utility model relates to the high pressure flange sealing devices of petroleum gas industrial, and in particular to a kind of gasket ring has diameter
To the well mouth sealing device of sealing function.
Background technique
Currently, the flange sealer used in industrial gas oil is played and tightening nut and compressing gasket ring
Sealing function.Since there may be defects in process for gasket ring and connection bolt, or in assembling process gasket ring not just,
Or nut such as does not tighten at the reasons, causes gasket ring poorly sealed, well head is caused to leak.
Summary of the invention
The purpose of this utility model is that: the well mouth sealing device that a kind of gasket ring has radial seal function is provided, solve because
The defect that nut is not tightened or gasket ring sealing surface has scratch and causes gasket ring poorly sealed, the effective stabilization for guaranteeing flange seal
Property, it avoids that leakage phenomenon occurs.
The technical solution of the utility model is: the well mouth sealing device includes left flange, right flange, gasket ring, double end
Bolt and liftout bolt, left flange are connect by stud and liftout bolt through gasket ring integral with right flange, and feature exists
In: set boss respectively in the axial end face of gasket ring, Zuo Falan, right flange contact surface on set gasket ring slot, the bottom of gasket ring slot respectively
The groove of boss is closed in portion's establishing, and gasket ring is mounted in gasket ring slot, and the boss of gasket ring fits snugly in the groove of gasket ring slot.
Wherein, the removal hole of screw thread is opened on the boss of gasket ring.
The utility model is interference fitted by the groove of the boss of gasket ring and the gasket ring slot of flange, is avoided because nut is not twisted
Tight or gasket ring sealing surface leaks caused by having scratch, fundamentally solves the problems, such as wellhead sealing, improves the leakproofness of flange
Energy.
Detailed description of the invention
Fig. 1 is the scheme of installation of the utility model.
Fig. 2 is Fig. 1 gasket ring schematic diagram.
In figure: 1 gasket ring slot, 2 studs, 3 gasket rings, 4 left flanges, 5 right flanges, 6 liftout bolts, 7 boss, 8 grooves, 9
Removal hole.
Specific embodiment
Technical solutions of the utility model are described in further detail with reference to the accompanying drawing.
As shown in Figs. 1-2, which includes left flange 4, right flange 5, gasket ring 3, stud 2 and ejection spiral shell
Bolt 6, Zuo Falan 4 are connect by stud 2 and liftout bolt 6 through gasket ring 3 integral with right flange 5, it is characterised in that: are being padded
The axial end face of ring 3 sets boss 7 respectively, Zuo Falan 4, right flange 5 contact surface on set gasket ring slot 1, the bottom of gasket ring slot 1 respectively
The groove 8 of boss 7 is closed in establishing, and gasket ring 3 is mounted in gasket ring slot 1, and the boss 7 of gasket ring 3 fits snugly in the groove 8 of gasket ring slot 1
In.
Wherein, the removal hole 9 of screw thread is opened on the boss 7 of gasket ring 3.
